This patent describes the cam switches that Tek introduced toward the end of the 1960s.

See also Patent 3,719,788 that covers switches with contacts mounted on opposite sides of the board, and Patent 3,584,174 covering the back-lit switches used in 7000-series scopes/plugins and other instruments, which also use low-inductance spring contacts on PCBs.
